For example, to convert 30° to radians we would multiply 30 by (π/180) and simplify:

= 30π/180
= 1π/6
= π/6 radians

So 30° is equal to π/6 radians.

How to Pronounce Greek Letters (American English) For Science and Mathematics:

Note: Though different than the above video, in your class you're more likely to hear mu is pronounced like "mew", nu is pronounced like "new" and upsilon is usually pronounced "oop·suh·laan".

You won't need to memorize or use all Greek letters in your trigonometry class. Some of the most common ones are α (alpha), β (beta), γ (gamma), θ (theta)—these are usually used to represent angles—π (pi), and ω (omega).
